Abstract: Objective To explore the clinical value of laparoscopic cholecystectomy with the “A-C-P” lines as anatomic markers. Methods We found out the patients who treated by laparoscopic cholecystectomy with the “A-C-P” lines as anatomical markers  in The Affiliated Hospital of Traditional Chinese Medicine Southwest Medical University from January 2018 to December 2021,and we analyzed the clinic date of the 1364 patients retrospectively to investigate the safety and efficacy of the“A-C-P” lines approach laparoscopic cholecystectomy procedure.Results The 1364 patients were successfully treated by laparoscopic cholecystectomy with the “A-C-P” lines as anatomic markers.The mean operation time was (35.20±11.30) min,the mean amount of intraoperatively bleeding was (10.62±5.51) ml,and the mean postoperative hospitalization time was (5.33±1.47) d.Seven cases had postoperative complications,including 3 cases of umbilical incision infection which were cured by clinic dressing change，and 4 cases of secondary common bile duct stones which were cured by endoscopic retrograde cholangiopancreatography or laparoscopic common bile duct exploration,without biliary tract injury and perioperative death. Conclusion We can finish a laparoscopic cholecystectomy with the “A-C-P” lines as Anatomical markers,our clinical practice preliminarily confirmed the safety of the procedure.
